Electric vehicle range prediction may include identifying vehicle transportation network information representing a vehicle transportation network, identifying expected departure temporal information, identifying a route from a first location to a second location in the vehicle transportation network using the vehicle transportation network information, identifying a predicted ambient temperature based on the first location and the expected departure temporal information, identifying vehicle state information for an electric vehicle, identifying an expected efficiency value for the electric vehicle based on the predicted ambient temperature, determining an expected operational range, such that, on a condition that the electric vehicle traverses the vehicle transportation network from the first location to the second location in accordance with the expected departure temporal information and the route, the expected operational range indicates an estimated operational range from the second location, and outputting the expected operational range for presentation at a portable electronic computing and communication device.
